Heat Loss to the Cooler Air That Moves Across the Surface

Question

Heat loss to the cooler air that moves across the surface of your body is called
A) radiation.
B) conduction.
C) convection.
D) evaporation.
E) transmission.

Accepted Answer

Convection is the transfer of heat through the movement of fluids or gases. In this case, cooler air is moving across the surface of the body, taking away heat from the body and causing heat loss. Radiation refers to the transfer of heat through electromagnetic waves, such as from the sun, and is not directly related to the movement of air. Conduction is the transfer of heat through direct contact, and evaporation is the process of liquid turning into vapor, which can cause cooling but is not directly related to moving air. Transmission is a broad term that can refer to the movement of any substance, including heat, but does not refer specifically to heat loss through air movement.
